Development of a novel Chimeric Antigen Receptor (CAR) for its use in Natural Killer (NK) cells for cancer treatment and beyond

Angela Madurga Alonso

The use of CAR technologies has revolutionized cancer treatment. Their unprecedented efficacy against B cell malignancies has opened the doors for a lot of excitement and research in the field. These synthetic receptors are composed of an antigen recogniti ...

Microfluidic characterisation reveals broad range of SARS-CoV-2 antibody affinity in human plasma

Didier Trono, Priscilla Turelli, Marc Emmenegger

The clinical outcome of SARS-CoV-2 infections, which can range from asymptomatic to lethal, is crucially shaped by the concentration of antiviral antibodies and by their affinity to their targets. However, the affinity of polyclonal antibody responses in p ...

Delivery of STING agonists for adjuvanting subunit vaccines

Li Tang, Bing Feng, Simon Bart M. Van Herck

Adjuvant is an essential component in subunit vaccines. Many agonists of pathogen recognition receptors have been developed as potent adjuvants to optimize the immunogenicity and efficacy of vaccines. Recently discovered cyclic GMP-AMP synthase-stimulator ...

Cytokine engineering for targeted cancer immunotherapy

Li Tang, Lucia Bonati

Cytokines are key modulators of the immune responses and represent promising therapeutics for a variety of cancers. However, successful translation of cytokine-based therapy to the clinic is limited by, among others, severe toxicities and lack of efficacy ...

Wdr1 and cofilin are necessary mediators of immune-cell-specific apoptosis triggered by Tecfidera

Yimon Aye, Sruthi Raja, Jesse Poganik, Kuan-Ting Huang, Yi Zhao

The mechanism-of-action of many electrohilic drugs remains poorly understood. Here, the authors use a redox-targeting approach to elucidate the basis for the innate immune cell toxicity of dimethyl fumarate, showing that it modifies Keap1 to trigger mitoch ...

Tumor-specific cytolytic CD4 T cells mediate immunity against human cancer

Hatice Altug, Alexander Mathis, George Coukos, Xiaokang Li, Yen-Cheng Liu, David Gfeller, Pedro Romero, Alexandre Harari, Amélie Cachot, Margaux Saillard, Georg Alexander Rockinger

CD4 T cells have been implicated in cancer immunity for their helper functions. Moreover, their direct cytotoxic potential has been shown in some patients with cancer. Here, by mining single-cell RNA-seq datasets, we identified CD4 T cell clusters displayi ...

Weevil pgrp-lb prevents endosymbiont TCT dissemination and chronic host systemic immune activation

Florent François Masson, João Pedro Alves Da Silva

Long-term intracellular symbiosis (or endosymbiosis) is widely distributed across invertebrates and is recognized as a major driving force in evolution. However, the maintenance of immune homeostasis in organisms chronically infected with mutualistic bacte ...

Metabolic and microenvironmental strategies to accelerate hematopoietic recovery post-aplasia

Vasco Ledebur de Antas de Campos

The procedure-associated mortality rate of bone marrow transplantations (BMT) remains close to 25%. The BMT is therefore only indicated for life-threatening diseases, with no replacement of this technology to be expected in the foreseeable future. Modest i ...

Genetic determinants of healthy human immune variance: from humoral response to microbiome diversity

Petar Scepanovic

Identifying the drivers of the observed interindividual variability of the human immune system is crucial to our understanding of infectious and immune-mediated diseases. The contribution of genetic and non-genetic factors to immunological differences betw ...

Paracrine Activin-A Signaling Promotes Melanoma Growth and Metastasis through Immune Evasion

Daniel Constam, Susanna Eveliina Kallioinen, Olivier Andreas Dubey, Patrick Mueller

The secreted growth factor Activin-A of the transforming growth factor beta family and its receptors can promote or inhibit several cancer hallmarks including tumor cell proliferation and differentiation, vascularization, lymphangiogenesis and inflammation ...

Dual angiopoietin-2 and VEGFA inhibition elicits antitumor immunity that is enhanced by PD-1 checkpoint blockade

Michele De Palma, Céline Wyser Rmili, Ece Kadioglu, Nicolo Rigamonti, Damya Laoui, Antonino Cassarà

Pathological angiogenesis is a hallmark of cancer and a therapeutic target. Vascular endothelial growth factor A (VEGFA) and angiopoietin-2 (ANGPT2; also known as ANG2) are proangiogenic cytokines that sustain tumor angiogenesis and limit antitumor immunit ...

Notch Signaling Regulates the Homeostasis of Tissue-Restricted Innate-like T Cells

Freddy Radtke, Ute Koch

Although Notch signaling plays important roles in lineage commitment and differentiation of multiple cell types including conventional T cells, nothing is currently known concerning Notch function in innate-like T cells. We have found that the homeostasis ...

Increased Myeloid Cell Production and Lung Bacterial Clearance in Mice Exposed to Cigarette Smoke

Alessandra Piersigilli

Pneumonia is a leading cause of hospitalization in patients with chronic obstructive pulmonary disease (COPD). Although most patients with COPD are smokers, the effects of cigarette smoke exposure on clearance of lung bacterial pathogens and on immune and ...

Mechanisms of tolerance induction by erythrocyte-targeted antigens

Alizée Jéléna Grimm

Immune-mediated disorders such as autoimmune diseases, graft-versus-host disease or allergies, are a major contemporary burden. Despite significant advances in the field of immunological tolerance, immunosuppressive drugs are still the current hallmark for ...
